yacc/bison build errors on current CVS

[Robert Millan <zeratul2 at wanadoo dot es>]

Hi!

I got a build error when trying to build from today's CVS sources on
i386-linux-gnu. The problem seems to be related to:

  http://gcc.gnu.org/ml/gcc/2003-01/msg01582.html
  (I tried "cd gcc/gcc && cat .cvsignore | xargs rm" as suggested by the
  response message but that didn't help.)

I'm using debian sid with:

  (host) gcc (GCC) 3.3.2 20030831 (Debian prerelease)
  flex 2.5.31
  bison (GNU Bison) 1.875a

And configured build gcc with:

  --prefix=/tmp/toolchain/install/ --enable-languages=c

Error log follows:
